I JUST BOUGHT MY FIRST 300E ON EBAY FOR 1000- USD(I KNOW,THE MOST EXSPENSIVE MB IS A CHEAP ONE!) IT STARTS UP AND RUNS WELL INITIALLY,AND THEN THE IDLE WILL START TO BE A LITTLE ROUGH AND THEN IT WILL STALL OUT AND TAKE ABOUT 15 MIN. BEFORE IT STARTS AGAIN. IT IS VERY INCONSISTANT,I HAVE DRIVEN IT 10 MILES OR SO BEFORE IT ACTS UP AND SOMETIMES IT WILL ACT UP IMMEDIATLY ON START UP. I'VE STARTED WITH REPLACING THE OVP RELAY TO NO AVAIL.
THIS WEEK I'M REPLACING THE FUEL PUMP RELAY AND THEN CAP/ROTOR+PLUGS. ANY SUGGESTIONS WOULD BE GREATLY APPRECIATED!

OH YEAH, I'M ALSO GOING TO REPLACE BRAKE PADS AND ROTORS. IS THERE ANY TRICKS OR TIPS?!
THANKS !!!!!
